The evidence is in the car insurance premiums ... step daughter moved to Aurora last year from southern Maryland ... her insurance is 3-4x what it is in Maryland.
The evidence for your daughter’s insurance premiums are not due to legal marijuana. Colorado has had a massive population influx as well as several massive natural disasters that have driven up our insurance rates. Last here there was a hail storm that ran over 1 billion in damages for insurance companies.

Also, my son wants to point out that you coasters keep moving to CO and ruining this beautiful state by dragging in your flipping irresponsible, liberal policies.
